  11. Physiology • Air in and Air out • Gas exchange • Saturations • Alveolar-arterial gradient • Metabolic • Angiotensin 1 to 2 conversion • Eicosanoid metabolism

  12. Gas in and out

  13. Peak Flow

  14. Volume Time

  15. Flow Volume Loop

  16. Pathology • Think Anatomy • Trachea • Bronchus • Alveolus • Endothelium • Interstitial space • Blood vessels • COPD • Respiratory Failure • O2 and oxygen therapy

  17. Tracheal Pathology

  18. Bronchus Pathology

  19. COPD • Pink puffer or Blue Blotter

  20. FVC/FEV1 ratio

  21. Respiratory Failure • Respiratory failure is present if PaO2 is less than 8 kPa - 60 mmHg. • It is sub-classified into one of two types of respiratory failure based on the level of PaCO2: • Type 1 respiratory failure: • PaCO2 is less than 6.5 kPa • PaO2 less than 8 kPa • Type 2 respiratory failure: • PaCO2 is greater than 6.5 kPa • PaO2 is less than 8 kPa

  22. O2 and oxygen therapy • Patients with chronic hypoxia from chronic lung disease • Poor PaO2 and good sats • Acute unwell hypoxic patients need 100% oxygen
